摘要：
The ketyl-induced reaction of [Ru-3(CO)(12)] with N,N-bis(diphenylphosphanyl)n-propylamine (dpppra) in THF resulted in the expected metal cluster [Ru-3(CO)(10)(mu-dpppra)] (2) in high yield. Compound 2 reacted in refluxing heptane with (PBu2H)-H-t affording a new derivative of the rare type of 46-valence electron clusters [Ru-3(mu-CO)(CO)(4)(mu-dpppra)(mu(3)-H)(mu-H)(mu-PtBu2)(2)] (3) in good yield. The related cluster [Ru-3(mu-CO)(CO)(4)(mu-dppa)(mu(3)-H)(mu-H)(mu-PtBu2)(2)] (4) (dppa=bis(diphenylphosphanyl)amine) was obtained in a similar manner in comparable yields. Compounds 2, 3, and 4 were spectroscopically characterized and their molecular structures in the solid were confirmed by single-crystal X-ray analysis.
